By Unknown Lamer from Slashdot's when-kde-and-qt-become-one department:KDE Community writes "The KDE Community is proud to announce a Tech Preview of KDE Frameworks 5. Frameworks 5 is the result of almost three years of work to plan, modularize, review and port the set of libraries previously known as KDElibs or KDE Platform 4 into a set of Qt Addons with well-defined dependencies and abilities, ready for Qt 5. This gives the Qt ecosystem a powerful set of drop-in libraries providing additional functionality for a wide variety of tasks and platforms, based on over 15 years of KDE experience in building applications. Today, all the Frameworks are available in Tech Preview mode; a final release is planned for the first half of 2014. Some Tech Preview addons (notably KArchive and Threadweaver) are more mature than others at this time."

By Unknown Lamer from Slashdot's a-bit-blunt department:An anonymous reader writes "Activities, technologies, equipment, or other matters regarding the US Department of Defense are a common topic on Slashdot, both as stories and in discussions. Despite that we seldom see stories regarding the senior leadership of DoD as we do for technologists, the political branches, and lately the NSA. Former Secretary of Defense Robert Gates, who served under both Presidents Bush and Obama, has released a rather biting memoir of his tenure as the Secretary of Defense. The Wall Street Journal has an excerpt: '... despite everyone being "nice" to me, getting anything consequential done was so damnably difficult — even in the midst of two wars. I did not just have to wage war in Afghanistan and Iraq and against al Qaeda; I also had to battle the bureaucratic inertia of the Pentagon, surmount internal conflicts within both administrations, avoid the partisan abyss in Congress, evade the single-minded parochial self-interest of so many members of Congress and resist the magnetic pull exercised by the White House, especially in the Obama administration, to bring everything under its control and micromanagement. Over time, the broad dysfunction of today's Washington wore me down, especially as I tried to maintain a public posture of nonpartisan calm, reason and conciliation. ... difficulties within the executive branch were nothing compared with the pain of dealing with Congress. ... I saw most of Congress as uncivil, incompetent at fulfilling their basic constitutional responsibilities (such as timely appropriations), micromanagerial, parochial, hypocritical, egotistical, thin-skinned, and prone to put self (and re-election) before country.' — More at The Washington Post"

By Unknown Lamer from Slashdot's news-for-people-who-don't-care department:Nerval's Lobster writes "In a keynote talk at this year's Consumer Electronics Show (CES) in Las Vegas, David Pogue (Yahoo's freshly minted technology columnist) suggested that the new 'Yahoo Tech' Website — a key part of the company's latest rebranding — would be targeted at 'normal' people as opposed to 'gearheads.' Based on a map that flashed on the giant screen behind him, which showed the 'normals' clustered in the middle of the country and the 'gearheads' restricted to the coasts, it's clear that Yahoo has embraced a divisive strategy that tries to equate Yahoo's brands with some sort of mythical 'middlebrow' audience that exists within clearly defined borders. (During his presentation, Pogue also flashed a slide that made fun of competing tech-news brands: The Verge was rendered as 'The Urge,' for example, while Gizmodo became 'Gizmoody.') The problem is that rigid audience of 'normals' doesn't exist, at least not in the way that Yahoo envisions. Large numbers of well-educated technology consumers — 'gearheads,' in Pogue's parlance — exist all over the country; to say otherwise is like suggesting that Wyoming is 100 percent Republican, or that everybody who lives in Florida hates snow. In other words, Yahoo's approach to tech content isn't merely schismatic; it's willfully unaware of the variety that exists among technology fans."

By Unknown Lamer from Slashdot's someone-has-to-do-it department:ananyo writes "By pouring cash into science and technology faster than its economy has expanded, China has for the first time overtaken Europe on a key measure of innovation: the share of its economy devoted to research and development. In 2012, China invested 1.98% of its gross domestic product (GDP) into R&D — just edging out the 28 member states of the European Union, which together managed 1.96%, according to the latest estimates of research intensity, to be released this month by the OECD. The figures show that China's research intensity has tripled since 1998, whereas Europe's has barely increased (see graph). The numbers are dominated by business spending, reflecting China's push in the manufacturing and information- and communication-technology industries."

By Soulskill from Slashdot's like-dr.-house-but-lazier department:theodp writes "Writing in the NY Times, Dr. Haider Javed Warraich shares a dirty little medical secret: doctors do 'Google' their patients, and the practice is likely to only become more common. And while he personally feels the practice should be restricted to situations where there's a genuine safety issue, an anecdote Warraich shares illustrates how patient search could provide insight into what otherwise might be unsolved mysteries — or lead to a snap misdiagnosis: 'I was once taking care of a frail, older patient who came to the hospital feeling very short of breath. It wasn't immediately clear why, but her breathing was getting worse. To look for accidental ingestions, I sent for a drug screen and, to my great surprise, it came back positive for cocaine. It didn't make sense to me, given her age and the person lying before me, and I was concerned she had been the victim of some sort of abuse. She told me she had no idea why there was cocaine in her system. When I walked out of the room, a nurse called me over to her computer. There, on MugShots.com, was a younger version of my patient's face, with details about how she had been detained for cocaine possession more than three decades earlier. I looked away from the screen, feeling like I had violated my patient's privacy. I resumed our medical exam, without bringing up the finding on the Internet, and her subsequent hospital course was uneventful.'"

By Soulskill from Slashdot's train-a-friendly-dolphin-to-use-KeePass department:Phopojijo writes "You can encrypt your password library using a client-side manager or encrypted file container. You could practice your password every day, keep no written record, and do everything else right. You then go in for a serious operation or get in a terrible accident and, when you wake up, suffer severe memory loss. Slashdot readers, what do you consider an acceptable trade-off between proper security and preventing a data-loss catastrophe? I will leave some details and assumptions up to interpretation (budget, whether you have friends or co-workers to rely on, whether your solution will defend against the Government, chance of success, and so forth). For instance, would you split your master password in pieces and pay an attorney to contact you with a piece of it in case of emergency? Would you get a safe deposit box? Some biometric device? Leave the password with your husband, wife, or significant other? What can Slashdot come up with?"

By Soulskill from Slashdot's how-many-transistors-can-dance-on-the-head-of-a-pin department:dcblogs writes "The technology industry has been coasting along on steady, predictable performance gains, as laid out by Moore's law. But stability and predictability are also the ingredients of complacency and inertia. At this stage, Moore's Law may be more analogous to golden handcuffs than to innovation. With its end in sight, systems makers and governments are being challenged to come up with new materials and architectures. The European Commission has written of a need for 'radical innovation in many computing technologies.' The U.S. National Science Foundation, in a recent budget request, said technologies such as carbon nanotube digital circuits will likely be needed, or perhaps molecular-based approaches, including biologically inspired systems. The slowdown in Moore's Law has already hit high-performance computing. Marc Snir, director of the Mathematics and Computer Science Division at the Argonne National Laboratory, outlined in a series of slides the problem of going below 7nm on chips, and the lack of alternative technologies."

By Soulskill from Slashdot's building-upon-building-things-to-build-things department:New submitter amasad writes "This post describes building a JavaScript virtual machine and an in-browser stepping debugger using the latest JavaScript generator feature. It's called debug.js. 'For the past few years I’ve been working on creating tools to help people learn programming on the web. I’ve worked on repl.it and open sourced the underlying technology which powered a few learn to code websites and until recently lead product engineering at Codecademy. Through all that, one thing I really wanted to see are the tools to make it possible to visualize code execution and step through code in the browser. To catch glimpse of what an ideal interactive learning environment would be you should check out Learnable Programming by Bret Victor. In addition to the educational benefits of such a tool, if matured it could be also useful for code instrumentation, web IDEs, and creating a foundation for writing other VMs on top of JavaScript (having the pausable machine state let's you not worry about the non-blocking environment). Ever since I've read about the ES6 Generators proposal, I’ve been toying with this idea in my head but it wasn't a real possibility until Ben Newman's Regenerator brought generators to the browser.'"

By Soulskill from Slashdot's at-least-they're-not-talking-about-their-breakfast department:New submitter natarnsco writes "The Dallas, Texas police chief has used an unusual weapon in his arsenal to announce firings and other disciplinary measures in the Dallas police force: Twitter. 'Dallas Police Chief David O. Brown has fired or disciplined 27 officers and employees in the last year. And every time he brings down the hammer, he announces it on Facebook and Twitter, specifying exactly who the men and women are and what they did. On Dec. 30, it was five officers and a 911 call operator.' The article goes on to say, 'Chief Brown is, as far as we know, unique among police chiefs in his use of social media. "I'm unaware of anyone else doing this," says Lt. Max Geron, who handles media relations at the Dallas Police Department. "If we weren't the first, we were one of the first." We checked out the Twitter profiles of various departments around the country as well and couldn't find a similar situation. The social media posts aren't an official policy of the DPD, but rather a "push for transparency" initiative, in Lt. Geron's words. "[It comes from] a desire to be more transparent and to get our message out to the greater community," he says.'"

By Soulskill from Slashdot's sign-of-the-times department:ananyo writes "From a few fragments out of a collection of 23-century-old Chinese bamboo strips, historians have pieced together what they say is the world's oldest example of a multiplication table in base 10. Each strip is about 7 to 12 millimeters wide and half a meter long, and has a vertical line of ancient Chinese calligraphy painted on it in black ink. The bamboo pieces constitute 65 ancient texts and are thought to be among the most important artifacts from the Warring States period before the unification of China. But 21 bamboo strips contained only numbers and, on closer inspection, turned out to be a multiplication table. As in a modern multiplication table, the entries at the intersection of each row and column in the matrix provide the results of multiplying the corresponding numbers. The table can also help users to multiply any whole or half integer between 0.5 and 99.5. The researchers suspect that officials used the multiplication table to calculate surface area of land, yields of crops and the amounts of taxes owed."

He has automated the process of modifying the source code to create custom currencies. Just enter in the name for your new currency, a logo image and set a few parameters (or accept the defaults), and you can have your own cryptocurrency. Source code and some customizations cost a bit extra. Once you have your own 'coin,' you just need to convince people that it is worth something."

Mick Ebeling of Not Impossible Labs read the story, was moved — and went to Sudan, where he set up a 3D printing lab which can produce an artificial arm for $100. Omar and others have received them, and Ebeling hopes that other organizations around the world will adopt his open-source design to help amputees, many of whom will never receive more conventional prosthetics."

By Soulskill from Slashdot's driving-us-crazy department:cold fjord writes "The Detroit News reports, 'A government report finds that major automakers are keeping information about where drivers have been — collected from onboard navigation systems — for varying lengths of time. Owners of those cars can't demand that the information be destroyed. And, says the U.S. senator requesting the investigation, that raises questions about driver privacy. The Government Accountability Office in a report released Monday found major automakers have differing policies about how much data they collect and how long they keep it. Automakers collect location data in order to provide drivers with real-time traffic information, to help find the nearest gas station or restaurant, and to provide emergency roadside assistance and stolen vehicle tracking. But, the report found, "If companies retained data, they did not allow consumers to request that their data be deleted, which is a recommended practice."'"

By Soulskill from Slashdot's just-small-enough-to-fit-inside-your-eye department:New submitter mpicpp points out that Intel has unveiled a PC called Edison, which fits into a casing the size of an SD card."Edison is based on Intel’s Quark chip, which it launched last year as its attempt to muscle in on that other flavour-of-the-month market: the so-called Internet of Things. It also reflects the company’s new-found keenness on the 'maker' community. Quark, a 22nm low-power x86 processor with two cores, sits inside Intel’s Arduino-compatible Raspberry Pi-alike Galileo board computer. Edison takes the same chip, connects it to a wee bit of LPDDR2 memory and Flash storage, and plugs in Bluetooth 4.0 Smart — aka LE — and Wi-Fi for broader connectivity."
